To all whom it may concern:

it known that I, GEORGE C. BREIDERT, a citizen of the United. States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and usefu Improvements in Car-Ventilatore, of wl ich the following is a specification.

invention relates to devices for ven- .ing railway cars or 'otherl vehicles or moving structures, of the type which operate on the principle of creating drafts across exhaust orifices by means of air rammmg faces disposed at substantially right angles lo the direction of travel of the car so that the movement of the car causes an impingement of air against the same, and arranged with respect to the exhaust orifices so that the impmging air will be directed unobstructedly across said orifices to produce a suction or vacuum in the device operating to withdraw foul air from the car.

The object'of the invention is t0 provide tain improvements in a car ventilator of type. These improvements consist et, of a novel contour for the air ramming 'faces whereby the impinging air is directed with certainty over the edges of the faces adjacent said exhaust orifices, and its wastte, by escapingover the 'other edges of said faces prevented or at least minimized; second, in certain devices and arrangements for bathing or intercepting dust, cinders, rain, and the like, and preventing the same from entering' the car through the exhaust orifices; third, in a construction of parts which ohviatcs the possibility of back drafts into the in 'whatever direction the wind may he hlowingr; and, finally, in certain other inu'nxivcd constructions, arrangements and levices relating to car ventilators to he hereinafter described and claimed.

ldlhile the invention preferably employs in combination, as shown in the drawings, the several mprovements disclosed, it is re alizcd that these features might be separately used to advantage in ventilators somewhat differently constructed from the terr-cd form shown, but of the same geninvention is illustrated in certain pre-l ferred embodiments in the accompanying" drawings1` whereinllie'urc 'l is a. fragmentary view, in perspective', of the top of a monitor deck car of ordinary construction, with a ventilator constructed in accordance with my invention attached to the deck sash so as to communicate with the car through one of the deck sash windows; Fig. 2 a view in perspective, on an enlarged scale, of the ventilator shown in Fig. l; Fig. 3, a sectional view on line 3-3 of Fig. 2; Fig. 4, a sectional view on line 4-t of Fig. 3; Fig. 5, a sectional view on line 5-5 of Fig. Q; Fig. 6, a detail sectional view taken on line 6 6 of Fig. 5 showing particularly the construction of the louvers and vertical baffling or defiecting strips; and Fig. 7, a fragmentary view in perspective, showing these constructions in fuller detail.

Like characters of reference designate like parts in the several figures of thevlrawings.

The ventilator of my invention has been shown and will be described in the position which it will assume when attached to the deck sash of the car. It should be understood that the device might be placed on the top of the car with the edges ofthe air ramming faces adjacent the exhaust orifices vertical instead of being horizontal, as they are when thc device is attached to the deck sash. The relative terms lippen lower, side, and end used in the description and claims herein, should be understood to refer to the respective paris of the device in its position attached to the deck sash. It is not intended, by the use of such terms, to limit the invention to this particular position of ventilator.

Referring tothe drawings, Q5 designates the deck of a monitor roof type of railway car and 26 the deck sash of the car.

The ventilator' consists of a box-like hollow structure, preferably inountcd on a hollow base or ring, provided with 'flanges for attachment to the deck sash of the car; the device beingr mounted over one of the deck sash window openings through which it is in communication with the interior of the car. The hase consists preferably of side members Q7 and top and bottom n'iembers 29,'which diver-,fre in the direction away from the car. The bottom member 29 is formed with drainage outlets 30. By its oblique position this member provides a gutter to Vintercept water which may find its way into the base or ring. Such water is discharged through the drainage openings 30. Theside and top and bottom members of the base are formed with tlangesl byv means of which -prevent the vsame from into the body of the ventilator is narrowed by partitions 32, preferably formed continuous with therto'pv and bottom members 28, 29, and g y which extend intothe body of the ventilator further, by, converging flanges 33 from the's'ides, top and bottom pf the base,

and serve to intercept foreign matter and through the ventilator. The body of the ventilator consists of a pair of air ramming faces 34, and anz-imperforate end 35. These parts may be made of one strip of metal suitably bent and secured to the base. The top and bottom of thebody portion of the ventilator are Opemcenstituting/air orifices 36 between the opp'ositely disposed air ramming faces 34.-. The latter' are preferably bent on the diagonal lines "sh7own so that the center portion of the face, in each case, constitutes a diamopd shaped wedge y37 which projects' out farthest at its center line 38, and from that line is inclined inwardly on opposite sides toward the exhaust orifices. This gives the edges 39 of the air ramming faces adjacent the exhaust orifices a central depression or bend, and also causes each triangular corner portion 40 of the face to slope inwardly from the corner ofthe face toward the central wedge portion 37. The purpose of this configuration is to direct '.the air impinging against the face toward the edges 39, and thence over the exhaust oriices, preventing or minimizing the lescape of air over the edge of the face adjacent'the closed end 35 of the ventilator. The air raniming faces, as a whole, are at right angles to the line of travel of the car. It has been found, however, by actual experiment, that by bending the faces on the diagonal lines, as above "described, a much greater efficiency is attained than if the faces were perfectly fiat. The central wedging portion divides the air and directs it toward the upper and lower exhaust orifices. The slight inward inclination of the corner portions of the face prevents the air from es caping'in any considerable volume over the outer end of the ventilator. The air rainming face is not specifically ,clfimed herein, beinglclaimed in my eti-'pending application Serial No. 7 67,088, filedh/Iay 12,1913.`

entering the car The exhaust oriicesnre preferably pro-l vided eachgrith a set of parallel louvers lll which extend acrossthe openings from one air rammin'g face to tlieother. vers are connected by sets of vertical bailling or deflecting strips 42, one set at each cf the devices adjacent the airramming faces but preferably spaced a short distance from the same. 'The louvers with lips 43 outwardly inclined with respect to the car. f

, The constructions just described have These louare preferably formed,

the like, and

l proven to be eminently well calculated to balile andintercept dust, cinders, rain and revent` the same from enter` tthe same time, they do nt in anyway hinderthe exhausting operation of the ventilator or give rise to chokinglor back drafts. The arrangement is such ,aste be effective, in both particulars noted, regardless may be blowing. rllhe vertical deflecting stripsv are particularly -well calculated' to prevent .cinders from entering the car through the ventilator. The ventilator, it

ing the car.

of-the direct-ion in which therwind will be seen, 1s open at the top. There is nothing to prevent cinders. from the locomotive dropping louvers 41.y If the vertical strips were through the spaces between omitted, the wind or the motion of the train might cause the cinders to impinge upon the `inside of the rear one of the air ramming faces and be therefrom deilected intoi'the car through the deck sash opening. Y,The

vertical defiecting strips adjacent`this face serve to break the velocity of .the cinders v and moreover, by standing between the inside of such face and the opening into the car, prevent any im'pinging cinders from reaching the opening. The cinders striking against the rear set of deflecting strips, are checked in their movement and precipitated out of the device through the lower set of openings. The horizontally extending louvers el similarly intercept and break the velocity of cinders Iwhich may blow into the upper exhaust orifice in ,directions trans verse or oblique to the louvers. vSuch cinders fall out of the lower exhaust orifice. The constant exhaust through the apparatus, together with the position -of the converging flanges 33 surrounding the opening between the body of the ventilator and Jthe base, fur'- ther serve' to prevent foreign matter in suspension .in the` airy from entering the car through the ventilator. lVhen the ventilator is arranged in vertical position, the converging fianges 33 serve the purpose of pro- `viding a gutter for collecting and discharging water which may be driven intozthe ventilator through the open sides thereof.

The ventilator above described is intended particularly forI steam lrailway service, although it might be used upon street cars. In order to give the device great strength and rigidity, having in view particularly this service on steam roads, the louvers an detiecting strips are made to serve'not only the function above described, but are also so constructed and.
